2,4-dinitrophenol fails to stimulate the breakdown of the soluble high energy intermediate of oxidative phosphorylation isolated from alcaligenes faecalis extracts once the intermediate is broken down, by other reactions, the coupling enzyme is prevented from reassociation with the electron. Chemical properties 2,4-dinitrophenol is a yellow, crystalline solid that has a sweet, musty odor it sublimes when carefully heated and is volatile with steam. Dinitrophenols are a class of manufactured chemicals that do not occur naturally in the environment there are six different dinitrophenols the most commercially important dinitrophenol, 2,4-di-nitrophenol (dnp), is a yellow solid with no smell it is used in making dyes, wood preservatives, explosives, insect control substances, and other.
